22ft of shark makes for a long day, but the company was amazing!

Time lapse video of today’s basking shark necropsy led by @shellspc.bsky.social. Three hours of work condensed into just over a minute. 🦈

It's the rounder, more "derpy" face that gives it away (that's a technical term)... also note it actually looks like a rock 🤷🏼‍♀️ #science

Our SPOT tagged shark, Tasha, has also been making moves! Her tag expires after 180 days (July-early January), so hopefully she'll ping again soon. The great thing about M tags is they never expire, so we hope to receive recapture reports for these sharks for many years into the future.

Thanks @ma-sharks.bsky.social for the flashback, this was an incredible necropsy made possible by your dedication to securing these fish when they wash ashore.

This female Porbeagle had 4 developing embryos. They are nourished by feeding on unfertilized eggs. The term for this strategy is Oophagy, meaning 'egg eating'.
You can see their yolk stomachs and some of the eggs they were feeding on in these photos. 🦈

My first #Bluesky post is a good one! Happy to announce the publication of "Morphometric Conversions for 33 Shark Species from the Western North Atlantic Ocean", a culmination of thousands of #shark measurements collected over 50+ years! OA here: spo.nmfs.noaa.gov/sites/defaul...
